LOOSE-LEAF BINDER.

Specification of Letters Patent.

Patented Jan. 16, 1917.

Application filed June 12, 1915, Serial No. 33,718. Renewed November 27, 1916. Serial No. 133,813.

To all whom it may concern Be it known that- I, JO N SCHADE, Jr., a

citizen of the United States, residing in the city of Brooklyn, county of Kings, State of New York, have invented certain new and useful Improvements in'Loose-Leaf Binders; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention pertains to improvements in loose leaf binders and has for its primary aim to provide an efficient device of the above character which may be cheaply manufactured.

A further object resides in the provision of a binder of the ring type wherein but few parts are employed, rendering the construction simple and of a durable nature.

Still further objects will be set forth hereinafter and those salient features of construction, arrangement and combination of parts on which protection is desired will be succinctly defined in the appended claims.

For a full understanding of the invention, reference is had to the following specification and the accompanying drawing, wherein:

Figure 1 is a top plan view of the invention with portions broken away; Fig. 2 is a longitudinal section of the body member with the spring mounted on the bridges thereof; Fig. 3 is a transverse sectional view taken about on line 3-3, Fig. 1; and Fig. 4 is a fragmentary perspective of one of the prong-carrying members.

' Referring more particularly to the drawings, wherein similar reference characters designate corresponding parts throughout, the inventionyin its preferred form, comprises a support or body, conslstmg of spaced bridges 2 integrally and rigidly connected by a brace member 3, each bridge having an apertured ear 4 extending outwardly therefrom to provide a suitable means for securing the body to the cover plate 5. The opposing faces of the bridges 2 are recessed, as at 6, into which are sprung the ends of a wire spring 7 so that the latter is normally bowed, Fig. 2. On the opposite sides of the recess 6, each bridge is formed in its upper edge with bearings 8 alining with the bearings of the companion bridge. In these bearings are journaled prong-carrying'mer'nbers 9, the'pron'gs 10 of which extend upwardly through suitable notches 11 of the cover plate 5 and supplement the opposing prongs to form the binder rings.

The prong-carrying members have inwardly extending or crank portions 12 each formed with a grooved seat 13 to receive the spring 7 and being offset or staggered with respect to the bent portion 12 of the companion prong-carrying member whereby the spring is distorted in reverse directions to give av good spring action to the prong members.

The cover plate 5, besides closing the bearings 8, also houses the spring and members 9 and defines with the brace member 3 the limits of swinging movement of the portions 12. This is a safeguard against opening the prongs too far although under usual conditions, the spring limits the opening move ment.

What is claimed is:

1. In a device of the character described, a rigid support, prong-carrying members rockably mounted thereon, and an end thrusting bow spring member engaging each prong-carrying member at single points that have staggered relation. 7

2. In a device of the character described, a rigid support, prong-carrying members rockably mounted thereon and each having a crank portion extending toward the other member in staggeredrelation to the crank portion thereof, and an end thrusting bow spring engaging each crank portion of the prong-carrying members.

3. In a device of the character described, a rigid support, prong-carrying members rockably mounted thereon and each having a crank portion extending toward the other member in staggered relation to the crank portion thereof, each crank portion having a grooved seat, and an end thrust bow spring engaging in the grooved seat of the prongcarrying members.

4:. In a device of the character described, a support, a longitudinally arranged spring thereon, and companion prong-carrying members journaled on the support on opposite sides of the spring and each having a crank. portion ofiset with respect to the crank portion of the other member and engaged with the spring.

5. In a device of the character described, a support including spaced bridges a wire spring mounted between the bridges in a spring manner, and a prong-carrying member journaled on the bridges on eachside of the spring and formed With an inwardly extending portion staggered relative to the corresponding portion of the other member and engaging the spring to distort the same in reverse directions.

6. In a device of the character described, a support comprising spaced bridges joined by a brace member, the opposing faces of the bridges being formed with recesses and their upper edges formed with bearings on each side of the recesses, a wire spring having its'ends sprung into the recesses so that the spring is bowed, a prong-carrying member journaled in the bearings on each side of the bridge recesses each prong'carrying member being formed with an inwardly extending crank portion provided with a grooved seat to receive the spring, the crank portions of the prong-carrying members being relatively staggered whereby the spring is distorted in reverse directions, and a cover plate for prong-carrying members and spring.

In testimony whereof I afiix my signature in presence of two witnesses.
